HGH is a polypeptide
that is synthetised by somatotroph cells of the anterior
lobe of pituitary gland. This hormone is built of single
polypeptide chain of amino acid residues. Despite marked
structural similarities between growth hormone from
different species only humans and primates hGH is active
in human exclusively. The main action of hGH is to stimulate
the liver and other tissues to produce IGF-1. Hepatic
IGF-1 is believed to be a homeostatic regulator of tissue
growth on the level of the whole organism. During childhood
development hGH is essential to promoting growth in
height. It stimulates the growth of bone and muscle
and organ development. HGH is the most abundant hormone
produced by the pituitary gland. The production of hGH
peaks during adolescence, then steadily drops with increasing
age, falling by 75% in most people after 60.
HGH(Human Growth Hormone) has been heralded by medical
journals, news programs and leading newspapers and magazines
as the modern day "Fountain of Youth". Research
has been conducted by the nation's top univerities and
medical labs and the hGH substance is produced by leading
pharmaceutical companies. |
